• • Basically done
  • Possibility may exist for "transaction hijacking"... likely a non-issue
  • Question about multiple transactions modifying the same resource
    • There is a currently commented out integration test.. it would involve "object locking"
    • Optimistic locking is one possible approach, OCFL library supports this
    • ACTION: Ben P to create ticket to use OCFL optimistic locking in transactions
      • Could potentially take advantage of an existing "prepare()" method
      • Record state of resource when session is open
      • Potentially some Fedora-level object locking

1. • • Open question has mutable head would be impacted
     • ACTION: Peter W to create a JIRA to investigate support for optimistic locking and mutable head
